Application filed March 28, 1914.

To all whom it may concern:

Be it known that I, KENNETH L. EDDY, a citizen ofthe United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cards for Loose- Leaf Devices, of which the following is a specification.

My invention relates to that class of devices such as are described in mv co-pending application, Serial No. 828,173. In these devices it is customary to secure to the lower edge of the card a metal pin which is de signed to register with numerals or characters printed upon the lower edge of the cards, the lower end of the pins being arranged to engage or to be engaged by a rod but practice has shown that as or bar generally called a rising bar. This bar is generally connected by means of toggles to a longitudinally movable bar, which has its forward end or an extension connected thereto extending out of the casing containing the cards, and is designed to be manually operated from the exterior of the casing. When the longitudinally movable bar is moved inwardly, it causes the rising bar to move upwardly, due to the action of the toggles. This bar. on its upward movement engages the lower ends of the metal pins and raises certain of the leaves above their normal plane or position. It is claimed that in a loose leaf device of this kind, it is impossible to lose a card, it being well known in the ordinary card indexes, that if a card gets out of its designated position that it is hopelessly Iost,,whereas in these devices, if for example, the pin is secured to the letter C, it will be raised with the indicator bar, numerically corresponding to theletter C, and this is true, regardless of where the card is placed in the box.- When all of the parts operate as they are designed to, this is true, these pins are attached to the cards by the ordinary ofiice employee, who is not at all. a skilled mechanic, that the pins do not always depend vertically from the cards, as they are merely held frictionally on the lower edge thereof. The result of this is that if they areti pped even very slightly, the rising bar will fail to, engage the lower end of the pin, and the-particular card in question will not be raised andismore hopelessly lost if anything, than in'the old device. Attempts have been made to overcome this by providing Specification of Letters Patent.

' means to clamp the pin firmly to the card.

This has proven objectionable in practice, because the cards are of fragile material and it is not practical to secure anything like a firm hold upon them. These devices are sold on the basis that the user will be able to save time by the use of this kind of a device, and these kinds of pins require considerable time and care in securing them properly, which constitutes a further objection.

My invention has for its object to provide a card to be used in this class of devices in which the pins will be positively prevented from lateral movement and materially reduce the size, which they have to be, and thereby secure additional room for printing letters or characters upon the bottom of the card, and at the same time to provide a con-' struction -which will permit'of the almost instantaneous attaching and detaching of the pin. My means of accomplishing the foregoing may be more readily understood by having reference to the accompanying drawings, which are hereunto annexedand are a part of this specification in which:

Figure 1, is a side elevation of a card provided with my new improvement. Fig. 2, is a sectional view of the same. enlarged detail view of tion of the device;

. Similar reference numerals refer to similar parts throughout. the entire description.

As shown in the drawings, 1 is a card. which is provided with a metallic edging 2, secured to the lower edge thereof. This edging is formed from a blank 3, which, as clearly seen in the detail view, is provided with a plurality of openings corresponding to the wide and narrow portions of the pin 4, which, it will be observed, has a tongue punched out of its central portion near its upper end leaving the wide part to engage one side of the card, and the narrow or punched out portion to engage the other. The blank 3, is then formed and clamped upon the lower edge of the card when it will be apparent to all persons skilled in the art, that it presents a space on one side which is fitted to and coincides with the narrow or punched out portions of the pin 4, while the other side is fitted to and coincides with the broader portion of the pin at. It will be apparent that as the pin is the same thickness as the metal edging, that a perfectly smooth surface-is afi orded, while the edges of the Fig. 8, is an that any pin engage the adjacent edges of the binding in such a manner as to absolutely prevent any lateral movement of any kind. I

Although I have only shown a single pin mounted upon the card, it will be apparent desired number can be mounted providing that they do not exceed the number of characters or indicia 0n the lower ed e of the card.

aving described my invention what I regard as new, and desire to obtain by Letters Patent is:

1. A card for loose leaf index devices provided with 'a metal edging, there being a plurality of perforations in said edging adapted to engage a metal clip pin to be detachably secured therein.

2. A card for loose leaf index devices having a metal clip pin frictionally securedto tudinally thereof, and an edging of suitable material provided with a plurality of perforations adapted to engage the edge of the clip pin andhold the same against lateral displacement. g a

In witness whereof I have signed the foregoing specification.
